Boiler room with two heat exchanger
The boiler , with two exchangers, is intended for installations where there is a second, auxiliary energy source, such as oil, gas, solid fuel boilers, etc. When there is no sun even then there is hot water. All boilers , are vertical with a leatherette casing , or even with a steel casing , in case of installation outdoors. Sigma Energy, has the know-how for studies of central systems for both domestic, commercial and industrial use.
